Char-Lynn torque amplifier

A guy on my old car board is trying to help someone make his '47 Hudson into handicap operation (sad story- guy fell out of a tree he was pruning, broke his back, paralyzed from waist down). State law says it needs power steering to be legal. They're wondering how to do it.

The Char Lynn system used a torque amplifier. Pretty hard to find a Char Lynn, but I think someone still sells the torque amplifiers. Eaton? Surplus Hydraulic? Anybody got a link?
 
You mean "torque GENERATOR."

They still sell under the name "Charlynn" but the company that owns the operation is Eaton.

I don't know if such a device is road legal though. If hydraulic pressure is lost it makes the vehicle practically impossible to steer. Odds are your DMV may have never even heard of such a thing, so asking will result in a "NO."

You may be better off retrofitting a conventional "pitman style" power steering box to the car, or even going with a modern aftermarket rack and pinion setup.

Most automotive power steering systems still maintained a mechanical connection between the steering wheel and the front wheels. A Char-Lynn system functions in the same manner. I would trust any of those systems way before I will ever trust the new "drive by wire" electric power steering systems, but that is a whole 'nother story.

You can find the Char-Lynn torque generators on Amazon. Brand new. About $700.

You can find the same thing on Ebay, or you can find a used one. Most of the used ones sell way too high considering they are used and condition is unknown.

OR, go to Ebay and do a search for Char-Lynn torque generator. Those things are also used on fork lifts and other industrial equipment. I just recently found a brand new one. It is slightly different from the run of the mill units found on old tractors, but will fulfill my needs quite nicely. Paid less than those used units are going for. Way less.
 
Thanks, everybody- I think I've got enough to go on now.

And you're right- "Upon further review", it is torque generator. Torque amplifier is that lash-up on International tractors. Or, looking at it from the other way, an Ampli-Torque is the same deal on a Moline. It just all gets so confusing. . .
 
Char-lynn makes a steering motor witch is hydraulic. They also make a torque generator that was installed on old tractors before they had power steering. You cut the steering shaft added it in and installed a hydraulic pump to give power steering. You still always had manual steering if something went wrong. Would work fine on an older car. A+I had them available the last time I looked. Not cheep though.
 
I know Crown electric lift trucks used that setup. It was on a SC lift truck . Although its a elect lift trk its a hydrolic assist system I don't know the cost though.
